Bug Agent execution Timed Out. The agent execution provider did not respond in time

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Every time i ask something in the Agent, is say the Agent execution timed out. Moreover after trying to fix the bug by reinstalling cursor, now the desktopApp doesn’t recognize that i have Pro plan or that I want dark theme.

Here is the request if it can help : Request ID: 9f4f0700-24fc-4e42-8aa6-7a187f156ac3

Additional Information

It’s the second time I have this bug. the first time it was fixed by itself when i launched cursor 2 days after. For each new day when I launch cursor, the agent timed out BUT when I quit the folder, quit Cursor and reopen my recent project the agent was able to respond me. Moreover my Pro plan was taking in account

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, yep this is a known bug. The extension host sometimes doesn’t register the agent execution provider before the timeout. It happens most often on Windows on 3.2.x and 3.3.x. The team is aware, no ETA for a fix yet.

Workarounds that help most users:

  • Reload Window: Ctrl+Shift+P then Developer: Reload Window or click Reload Window in the error popup.
  • Legacy Terminal: Cursor Settings > Agents > enable Legacy Terminal.
  • Start Cursor with extensions disabled to rule out a conflict: run cursor --disable-extensions in a terminal. If the error goes away, one of the extensions is causing it, often Git Blame and similar. See Initializing extensions... breaks extensions functionality and slows down Cursor IDE
  • Full restart of Cursor, close all windows, not just minimize.

You already noticed reopening the project helps. That is the same kind of extension host re-init, so the symptom matches.

About the Pro badge and theme after reinstall, that is separate and not related to the timeout.

  • If Pro didn’t show up, sign out and sign in again via Cursor Settings, top right on the account page. Usually the status updates right away.
  • Theme: after a full reinstall settings reset, so just set a dark theme again: Ctrl+K Ctrl+T then pick Dark+.

If the timeout still happens regularly after the workarounds, send:

  • your list of enabled extensions
  • a screenshot from Ctrl+Shift+P then Developer: Open Process Explorer so we can check if extensionHost is stuck.

If we get an update on the fix, I’ll post it here.
